146: - major bug is fixed in STD format (1E7 sq prints 1);
147: - major bug is fixed in READ intrinsic (socket). This bug was introduced
148: by a new feature in glibc.
149: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
150: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
151: "ALL" IMPLICIT when it runs in interactive mode;
152: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
153: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
154: to use SAVE to manipulate global variables;
155: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
156: subroutines;
157: - fix major memory access violation in evaluation subroutine. Only occurs
158: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
159: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
160: when X was a vector or a table.
1.63 bertrand 161: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

171: Known escape sequences are \", \b, \n, \t, \x?? and \\.
1.60 bertrand 172: * Sun Mar 06 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2)
173: - Ncurses is upgraded to 5.8;
174: - ALARM is fixed by filling isdst field;
175: - catch ECONNRESET in write intrinsic to return an execution error instead of
176: system one;
177: - fix a typo in HELP intrinsic;

1.58 bertrand 180: - libmtmalloc is now default Solaris allocator;
1.56 bertrand 181: - ncurses is upgraded;
1.60 bertrand 182: - regression introduced by 4.0.19 is fixed in signal management.
1.59 bertrand 183: Interruption1() could be called from itself and raises bus error (on sparc) or
1.55 bertrand 184: segmentation fault;
185: - sqlite is upgraded to 3.7.4;
1.54 bertrand 186: - OpenSSL is upgraded to 1.0.0c;

1.53 bertrand 189: - gnuplot is upgraded to 4.4.2 due to major bugs.
1.52 bertrand 190: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
191: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
192: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
193: corruption. As internal memory management have been improved, a best fit
194: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 195: - gnuplot is upgraded to 4.4.1;
196: - deadlock is fixed in signal handlers: same mutex was used in standard
197: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
198: and signal handlers. A new signal handler specific mutex is added;
199: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
200: that has to be evaluated by ->NUM;
1.49 bertrand 201: - rplfile build process is modify to be sure that rplfile is not modified
202: after rpl build stage (to be sure that rplfile checksum is not modified after
203: rpl compilation);
1.51 bertrand 204: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
205: modified to remove yacc code and renamed;
1.47 bertrand 206: - some workarounds have been written to not use buggy klibc SystemV IPCS.
207: ABORT now works on eComStation;
208: - sqlite is upgraded to 3.7.2;
209: - bug is fixed in software interrupts. When both process have different PID,
210: parent process was not interrupted if it is not group master process. To fix
211: this bug, SIGINJECT signal is not sent by child process but by control thread
212: in parent process;
1.46 bertrand 213: - minor bug is fixed in data injection (POKE) that does not work as expected
214: when child process is protected by NRPROC.
1.44 bertrand 215: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 216: - --enable-sysv-sems is added to configure script to use SystemV semaphores
217: functions instead of POSIX functions. This function is disabled or forced on
218: systems that does not provide correct POSIX or SysV semaphores subsystem;
219: - a dirty but not quick patch is written to workaround broken siginfo
220: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 221: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 222: (Unix PID);
1.41 bertrand 223: - some OpenBSD's hacks are added;
224: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 225: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

227: - in transliteration subroutine : '\r' is added after all '\n' in OS/2 port;
1.39 bertrand 228: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
1.40 bertrand 229: or freeaddrinfo;
1.39 bertrand 230: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
231: - major bug is fixed in CHR intrinsic when obtained character is not printable;
232: - Lapack is upgraded to 3.2.2;
1.37 bertrand 233: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
1.36 bertrand 234: - TOKENIZE is now able to convert escape sequences;
235: - ATPOKE and CLRATPOKE new intrinsics are added;
236: - --enable-full-static configure flag is added. With this flag, mysql and
237: postgresql libraries are statically linked in rpl executable;
238: - units Makefile is modified to avoid readline and ncurses usages;
1.37 bertrand 239: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 240: - units is upgraded to 1.88;
241: - another major bug is fixed in the same variable creation subroutine.
242: Level 0 and 1 variables adresses were swapped when a global variable masked
243: a name of RPL/2 routine;
1.35 bertrand 244: - major bug is fixed in global variable creation subroutine. When a global
245: variable was created and when a local variable existed with the same name,
246: computed address of global variable was wrong;
247: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
248: is forced in front of all libraries.
1.34 bertrand 249: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
250: - BACKTRACE intrinsic is added;
251: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
252: when this structure is included in IFERR/THEN/END structure and when an error is
253: caught;
254: - major bug is fixed in analyse() subroutine. When evaluation() returned error
255: in a compiled program, analyse() caught this error twice and randomly aborted
256: with a segmentation error;
257: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
258: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
259: signals;
260: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
261: matrix.
1.33 bertrand 262: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
263: - minor bug is fixed in evaluation() subroutine. With this patch, same program

272: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
273: linux (false mremap() prototype);
274: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
1.30 bertrand 275: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)

278: - major bug is fixed in IFERR structure. Only occurs in compiled program;
279: - major bug is fixed in copie_objet() and liberation(). Only concerns
280: format in FCH (file descriptor) and SCK (socket descriptor);
281: - debug routines are improved;
282: - PROCID is added;
283: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
284: and to not use swap;
1.26 bertrand 285: - major bug is fixed in sql support. SQL connections were closed in all chield
286: process;
287: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
288: discovered in Solaris thread safe allocators (libmalloc and libumem) that
289: are first fit class allocators. Solaris libmtmalloc works better and is
290: a best fit class allocator but its performance is poor than ptmalloc3
291: performance;
1.24 bertrand 292: - major bug is fixed in ROW+ intrinsic (new row was not added where it
293: should);
294: - minor bugs are fixed in interruptions.c (semaphores values when error is
295: caught);
296: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
297: created by SPAWN;
298: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
299: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 300: - ONEXIT is renamed in ATEXIT;
301: - ONEXIT new intrinsic is added.
1.20 bertrand 302: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
303: - major bug is fixed in static and shared variables initialization subroutine.
304: This bug only occurs when RPL/2 tries to create a shared or static variable
305: from an expression;
306: - major bug is fixed in copie_etat_processus(). A field that contains
307: information about shared variable was not copied to new processus structure;
1.19 bertrand 308: - some little memory leaks are fixed in evaluation(), recherche_type() and
309: sequenceur(). They only occured when syntax error were caught;
310: - IMPLICIT causes execution error instead system error;
311: - Hurd support is improved but currently broken because Hurd does not support
312: SIG_INFO. Work in progress;
313: - OpenBSD specific support is removed from sources;
314: - support for Mac OS X and Windows/Cygwin is added.

353: rplc (RPL/2 compiler).
1.13 bertrand 354: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
355: - in formatted file, string format returned a variable length string even if
356: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 357: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 358: - keyed access files support is added. Currently, only formatted files are
359: supported;
360: - direct access files support is added. Currenlty, these files can only be used

1.12 bertrand 366: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
367: each execution (md5 and sha1 sums) to enhance security. If one of these tools
368: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
369: on a non recoverable system error;
370: - openssl and sqlite3 libraries are added;
371: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
372: variable indicates RPL/2 root directory. If it is not set, root path
373: is given by configure script (d_exec_path);
1.11 bertrand 374: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

401: - PULPRFL does not abort on BUG() but on execution error;
402: - TRIM, REPL and TOKENIZE are added;
403: - sockets options are now set before bind();
404: - shutdown() is added to all connected sockets;
405: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
406: list argument and inexistant elements).
407: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
408: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
409: signals sent to main process were not caught because DAEMON did not replace
410: old pid by new one;
411: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
412: evaluation when an error is reported from a subroutine in another subroutine.
413: For example, error was not caught in following program when it is executed with
414: -p option :
415: TEST << iferr TEST2 then end >>
416: TEST2 << 0 inv >>
417: - major bug is fixed in variable management. Some local variables were
418: seen as global ones;
419: - major bug is fixed in rplcore. Rplcore entered in dead lock when
420: script file contains a multibyte character;
421: - IN intrinsic is added;
422: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
423: returned false ;
424: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
425: programs;
426: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
427: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
428: strings were never closed;
429: - some bugs have been fixed in file management;
430: - RPL/2 can now be run on EBCDIC systems (OS/390);
431: - major bug is fixed in -A command line option (NULL character is missing);
432: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
433: made by blocks (1024 bytes). When an incomplete multibyte sequence is
434: encountered at end of block, subroutine aborts with an execution error;
435: - major bug is fixed in OPEN (TCP/IPv4 sockets).
436: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
437: - DISP now locks stdout;
438: - rpliconv is added to replace standard iconv provided by operating system.
439: Indeed, conversion between different encodages requires transliteration
440: that is not offered by some iconv utility;
441: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
442: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
443: not be found), SYSEVAL enters in a dead lock;
444: - fprintf is replaced by some functions that allow transliterations between
445: locales;
446: - '"' can now be used in strings ("\"");
447: - iconv is called with -c in preprocessor stage. It is done to write
448: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
449: - double free is fixed in liberation() (type SQL, only occurs when locale is
450: set);
451: - LOCALIZATION, UCASE and LCASE are added;
452: - major bug is fixed in EXIT intrinsic that was able to return a false
453: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
454: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
455: used in onLoading from shared library, USE was pushed on stack as algebraic
456: expression;
457: - libiconv is upgraded to 1.13.1;
458: - gnuplot is upgraded to 4.2.6;
459: - gsl is upgraded to 1.13.
460: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
461: - pipe() is overwritten by a macro to avoid a system error. Communication
462: between process are done with pipes and these pipes are managed by a
463: specific asynchrone thread. If a script try to create more threads than
464: management thread can destroy, you can quickly achieve maximum number of
465: opened files and pipe() shall return a system error. This macro tries to create
466: pipes. If pipe() function returns an error, macro waits and retries. If
467: number of retries is greater than a hardcoded value, macro returns an error;
468: - major bug (deadlock) is fixed in process and thread management. I hope
469: this bug shall be the last one;
470: - major bug is fixed in DET intrinsic (determinant was computed without LU
471: diagonalization);
472: - SWAPCNTXT is added;
473: - minor bug is fixed in Makefile.am (licences rule).
474: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
475: - some bugfixes are added in process management;
476: - all process management is rewritten to avoid usage of defunct process
477: or thread number;
478: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
479: was called before a pending interruption5 (SIGFSTOP), signal handler uses
480: a freed semaphore and corrupts heap;
481: - CLRERR is added to erase previous errors;
482: - ERRN and ERRM return exception message and number;
483: - major bug is fixed in interruptions.c. All signal are now bufferised
484: when semaphore_liste_threads is null to avoid deadlock. This bug only
485: occured when STOP was sent to a dying thread or process (when this thread or
486: process was running retrait_thread());
487: - matrix rank is computed before matrix inversion;
488: - file locks are added to stdin and stdout. stderr is not locked because
489: all messages written by signal handlers are sent to stderr;
490: - configure.in script is modified to test gcc version and avoid a bug in
491: gcc older than 4.4;
492: - some benchmarks have been done :

564: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
565: process is killed;
566: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
567: know typeof() intrinsic function. This function is not standard but exists
568: under Sun Studio, gcc, and maybe some others compilers. If this function does

611: static variable that is shared by multiple threads;
612: - '->' intrinsic is improved. All object copies have been avoided;
613: - -n flag is added to catch HUP signal. stderr and stdout are redirected
614: to a file, stdin is redirected to /dev/null when control process is killed;
615: - a mutex is added to each object (before this modification,
616: RPL/2 used a global mutex and performances in multithreaded programs were very
617: poor.);

632: that all programs that worked with old SQL intrinsic can now work with
633: SQLQUERY. With all new programs, you can open a real connection to databases;
634: - NRPROC is added. This new intrinsic is used to catch error from child
635: process. Without NRPROC, any errors returned by child process cause
636: main process to abort;
637: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
638: starts a new process). There are no mutexes in RPL/2 because all spawned process
639: use specific context. Nevertheless, shared variables and associated mutexes

779: before starting interrupt evaluation;
780: - -f parameter is added when iconv is called;
781: - as old file program was bugged, a new option is added to configure script.
782: When configure is called with --disable-encoding-autodetection, make does not
783: try to detect source encoding. Please, do not use if RPL/2 can be built
784: without this option !
785: - new garbage collector (and more efficient) is written;

789: - -p option is added. With this option, all scripts are compiled before
790: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
791: 40% faster;
792: - read and write operations in pipe() are rewritten to be sure that such
793: operations are atomic;
794: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

988: With STATIC, next variables created by '->' are static;
989: - PROTECT and UNPROTECT are added to protect variables against write
990: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
991: versions of PROTECT and UNPROTECT that only deal with global variables
992: (see RCL/SAVE);
993: - variable management routines have been rewritten. The new ones are
994: uncompatible with the old ones. Before these changes, a local variable
995: was exported to a child subroutine, but cannot be modified into this
996: child subroutine. Now, a local variable is accessible only in its subroutine;
997: - SAVE intrinsic is added to manipulate global variables;

1318: fine...);
1319: - NOT is not correctly formatted in formateur.c:
1320: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1321: with a NOTZ function !
1322: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1325: - RPL/2 is tested with efence and valgrind;
1326: - configure.in script is modified;
1327: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1388: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1389: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1390: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1407: - SCLS is added;
1408: - DRWS now uses COLS to draw 2D graphics;
1409: - PPAR and SPAR are written. SPAR returns a list that contains the
1410: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1411: statistical variable, or "DISABLED" if its type is not one of the type of
1412: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1413: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1414: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1415: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1416: disabled. Arguments of EXTERNAL are case sensitive because the external
1417: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1418: of known external functions but add the new list to the last. { "all" }
1419: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1420: external names of the known functions;
1421: - mkrplso.in is modified.
1422: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1423: - vim syntax file is upgraded;
1424: - a minor mistake is fixed in recherche_instruction_suivante();

1435: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1436: VISIT does not find a name in level 1;
1437: - configure.in script is modified to add a new test (--enable-debug
1438: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1439: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1440: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1441: 'MATRIX' { 2 2 3 } GETR;
1442: - LOGSCALE intrinsic is improved and now, it can be used as
1443: { "main" "auxiliary" X Y } LOGSCALE;
1444: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1445: same than AXES:
1446: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1447: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1448: { { -10 10 } "automatic" } SCALE.
1449: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1450: because it changes only the dimension of the screen. To have a logarithmic
1451: scale, you must use LOGSCALE intrinsic:
1452: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1453: screen on second scale;
1454: - { X X } autoscale and { Y Y } logscale are now invalid;
1455: - *D is added (depth multiplication, for 3D graphics);
1456: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1457: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1458: - a major bug is fixed in GETI instrinsic when it is used with a name
1459: that contains a matrix or a vector (bad upper bounds conditions in
1460: incrementation);
1461: - DISP intrinsic now uses the 33-th flag. When it is not set
1462: (default), a final carriage return is sent to the terminal;
1463: - AXES intrinsic only takes a list that can contains the keywork
1464: "main" or "auxiliary". Before this modification, this keyword was in
1465: the first stack level;
1466: - vim syntax file is upgraded;
1467: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1468: option;
1469: - LAST is now disabled in the main loop of INT intrinsic;
1470: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1471: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)

1474: in 0);
1475: - LAST is disabled in the main loop of DRAW intrinsic;
1476: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1477: evaluation of an equation, the system stack is returned corrupted to the

1513: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1514: is a quick and dirty workaround...);
1515: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1516: - rplconvert is improved.
1517: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)
